Description

Technical Field

[0001] This specification relates to the field of mechanical structure design, and in particular to a flipping assembly. Background Technology

[0002] The flip-up mechanism of a flip-up device typically relies on a gear transmission system. While gear transmission systems can effectively transmit power and control angles, their tooth backlash and minute tolerances in the transmission chain make them prone to slight structural wobble when stationary due to vibrations (such as low-frequency resonance) or external forces (such as user pressure). This slight wobble not only generates abnormal noises during operation, affecting the user experience, but also directly leads to a negative impression of the product's structural strength and manufacturing process.

[0003] Therefore, it is desirable to propose a flip cover assembly that can reduce the slight wobbling of the gear transmission system through structural design, thereby improving the user experience. Summary of the Invention

Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified elements; the device may also include other steps or elements.

[0019] This specification provides a flipping component in some embodiments.

[0020] Figure 1 This is a schematic diagram of the overall structure of the flipping assembly shown in some embodiments of this specification; Figure 2 This is a schematic diagram of the internal structure of the flipping assembly shown in some embodiments of this specification; Figure 3 This is a schematic diagram of the internal planar structure of the flipping assembly according to some embodiments of this specification.

[0021] In some embodiments, such as Figures 1 to 3As shown, the flipping assembly 1 includes: a main transmission component 11, which includes a main gear 111 with a transmission shaft, a motor 112, and a motor bracket 113. The motor 112 is mounted on the motor bracket 112, and the rotating shaft of the motor 112 is connected to the transmission shaft 111-1 of the main gear; an auxiliary transmission component 12, which includes a secondary gear 121 with a transmission shaft and a rotation transmission shaft 122. The secondary gear 121 meshes with the main gear 111, and the rotation transmission shaft 122 is embedded in the transmission shaft 121-1 of the secondary gear and is in close cooperation with the transmission shaft 121-1 of the secondary gear; a tensioning component 13, which includes a tensioning belt 131 sleeved on the transmission shaft 111-1 of the main gear and the transmission shaft 121-1 of the secondary gear; and a flipping component 14, which is connected to the rotation transmission shaft 122. When the rotation transmission shaft 122 rotates, it drives the flipping component 14 to flip.

[0022] The main drive component 11 refers to the component in the flipping assembly 1 that achieves active transmission under the action of electrical energy.

[0023] The main gear 111 refers to the gear in the main transmission component 11. The drive shaft 111-1 of the main gear is the power transmission hub of the main gear 111. In some embodiments, the drive shaft 111-1 of the main gear is fixedly connected to the main gear 111 or integrally formed with it, and the axis of the main gear 111 overlaps with the axis of the drive shaft 111-1 of the main gear in three-dimensional space.

[0024] The motor 112 is a device that converts electrical energy into mechanical energy, and the motor 112 can provide power for the transmission of the main transmission component 11. In some embodiments, the motor 112 can be any one of a servo motor, a stepper motor, etc. In some embodiments, the rotating shaft (i.e., the output shaft) of the motor 112 is fixedly connected to the transmission shaft 111-1 of the main gear.

[0025] The motor bracket 113 is used to fix the motor 112. In some embodiments, the motor bracket 113 can be disposed at any position of the motor 112. This is merely an example. Figure 1 As shown, the motor bracket 113 can be installed on the side of the motor 112 near the main gear 111.

[0026] Auxiliary transmission component 12 refers to the component that realizes power conversion in the flipping assembly 1.

[0027] The secondary gear 121 refers to the gear in the auxiliary transmission component 12. The drive shaft 121-1 of the secondary gear is the power transmission hub of the secondary gear 121. In some embodiments, the drive shaft 121-1 of the secondary gear is fixedly connected to or integrally formed with the secondary gear 121, and the axis of the secondary gear 121 overlaps with the axis of the drive shaft 121-1 in three-dimensional space. In some embodiments, the pitch circle diameter of the primary gear 111 is smaller than the pitch circle diameter of the secondary gear 121.

[0028] The rotating transmission shaft 122 is used to realize the transmission between the secondary gear 121 and the flipping member 14. In some embodiments, the diameter of the rotating transmission shaft 122 is smaller than that of the transmission shaft 121-1 of the secondary gear. The transmission shaft 121-1 of the secondary gear has a through hole along its axial direction. The rotating transmission shaft 122 is fixedly embedded in the through hole, thereby achieving a tight fit with the transmission shaft 121-1 of the secondary gear.

[0029] The tensioning element 13 provides tension to the main gear 111 and the auxiliary gear 121. The tensioning belt 131 refers to the belt body used to provide tension to the main gear 111 and the auxiliary gear 121. In some embodiments, the drive shaft 111-1 of the main gear and the drive shaft 121-1 of the auxiliary gear are respectively provided with mounting grooves on the sidewalls of the ends near or away from the motor 112, and the tensioning belt 131 is fitted into the mounting grooves. Here, the sidewall refers to the wall surface perpendicular to the axis of the drive shaft.

[0030] In some embodiments, the tension band 131 may be made of materials such as rubber or silicone. In some embodiments, the tension band 131 may apply tension to the main gear 111 and the secondary gear 121, and the tension can be understood as the friction between the tension band 131 and the gear. This arrangement ensures that when the flipping component 14 needs to be flipped, the gear set must simultaneously overcome the tension and the meshing force of the gears.

[0031] The flipping component 14 refers to the component that needs to be flipped. In some embodiments, one end of the flipping component 14 is fixedly disposed at the end of the rotation transmission shaft 122 near or away from the secondary gear 121. With this configuration, when the rotation transmission shaft 122 rotates, it can drive the flipping component 14 to rotate synchronously around the rotation transmission shaft 122, thereby realizing the flipping function.

[0032] In some embodiments, the flipping element 14 is a display screen or a cover. The display screen refers to a screen used to display content. For example, the display screen can be any of an electronic display screen, a control panel, etc. The cover refers to a cover used to achieve shielding, protection, or sealing. For example, the cover can be a protective cover (such as an interface baffle, an electrical cover, an electric door, etc.), a storage cover (such as a trash can lid, a vending machine dispensing baffle, etc.), etc.

[0033] In some embodiments, the flipping assembly 1 has a manual flipping mode and an electric flipping mode. The manual flipping mode refers to the mode in which the user manually flips the flipping component 14, and the electric flipping mode refers to the mode in which the motor 112 drives the flipping component 14 to flip.

[0034] Taking manual flipping as an example, the transmission process of the flipping component 1 is as follows: the user presses the flipping part 14; the flipping part 14 drives the rotating transmission shaft 122 to rotate; the rotating transmission shaft 122 overcomes the tension force and the meshing force of the gears, and drives the secondary gear 121 to rotate; the secondary gear 121 drives the main gear 111 to rotate; the main gear 111 drives the motor 112 to rotate.

[0035] Taking electric flipping as an example, the transmission process of flipping component 1 is as follows: The user inputs a flipping command through the terminal device; the motor 112 receives the flipping command and starts working. The rotating shaft of the motor 112 overcomes the tension force and the meshing force of the gears, driving the main gear 111 to rotate; the main gear 111 drives the secondary gear 121 to rotate; the secondary gear 121 drives the rotating transmission shaft 122 to rotate; the rotating transmission shaft 122 drives the flipping component 14 to rotate.

[0036] The aforementioned terminal device is communicatively connected to the flip component 1, allowing the user to interact with it. For example, the terminal device can be any of a mobile phone, computer, remote control, or buttons. A flip command is an instruction that controls the flip cover 14 to flip. For example, a flip command may include the angle at which the flip cover 14 flips.

[0037] It is worth noting that the above-described flipping component 1 is only an example. In other embodiments, the flipping component 1 may also include multiple intermediate gears in addition to the main gear 111 and the secondary gear 112, and the tension belt 13 may be sleeved on part or all of the main gear 111, the secondary gear 112, and the multiple intermediate gears. Alternatively, multiple tension belts 131 may also be sleeved between the main gear 111, the secondary gear 112, and the multiple intermediate gears.

[0038] In the technical solution where no tension belt is used between the gear sets, the gear transmission only needs to overcome the meshing force of the gears. However, in some embodiments of this specification, the technical solution where a tension belt is used between the gear sets requires the gear transmission to overcome both the tension force and the meshing force of the gears. That is, compared to the technical solution where no tension belt is used between the gear sets, the technical solution of this specification requires overcoming a greater force for the relative rotation between the gears. Therefore, it is less prone to slight wobbling under vibration (such as low-frequency resonance) or external force (such as user pressure), thereby improving the user experience.

[0039] In some embodiments, such as Figures 1 to 3As shown, the flipping assembly 1 also includes a housing 15, within which the main drive component 11, auxiliary drive component 12, and tensioning component 13 are disposed. The housing 15 protects the main drive component 11, auxiliary drive component 12, and tensioning component 13 from damage. In some embodiments, the motor bracket 113 can be fixed to the housing 15 by welding, bolting, or other methods, thereby placing the main drive component 11, auxiliary drive component 12, and tensioning component 13 within the housing 15, while at least a portion of the flipping component 14 is disposed outside the housing 15. This arrangement ensures the flipping function of the flipping component 14 while extending the service life of the flipping assembly, further improving the user experience.

[0040] In some embodiments, housing 15 is the housing of a specific device corresponding to the flip assembly 1. For example, when the device to which the flip assembly 1 is applied is a tablet computer, housing 15 is the housing of the tablet computer.

[0041] In some embodiments, the two ends of the rotating transmission shaft 122 are respectively mounted on the housing 15.

[0042] In some embodiments, such as Figure 2 and Figure 3 As shown, the flipping assembly 1 also includes at least two fixing members 16. Each fixing member 16 has a snap-fit ​​hole along the axial direction of the rotating transmission shaft 122. Both ends of the rotating transmission shaft 122 are rotatably fitted into the snap-fit ​​holes of the at least two fixing members 16. The at least two fixing members 16 are fixed to the housing 15 by bolts or welding. This arrangement allows the rotating transmission shaft 122 to rotate relative to the housing 15, thereby enabling the rotating transmission shaft 122 to drive the flipping assembly 14 to flip.

[0043] Figure 4 This is a structural schematic diagram of the tensioning element shown in some embodiments of this specification; Figure 5 This is the second structural schematic diagram of the tensioning member shown in some embodiments of this specification.

[0044] In some embodiments, such as Figure 4 and Figure 5 As shown, the tensioning element 13 also includes a torsion spring 132, a tensioning wheel 133, a cantilever 134, and a torsion spring fixing seat 135; the torsion spring fixing seat 135 is fixedly connected to the motor bracket 113; both ends of the torsion spring 132 are fixedly connected to the torsion spring fixing seat 135 and the cantilever 134 respectively; one end of the cantilever 134 is rotatably connected to the torsion spring fixing seat 135; the other end of the cantilever 134 is rotatably connected to the tensioning wheel 133; the torsion spring 132 drives the tensioning wheel 133 to compress the tension belt 131.

[0045] The torsion spring 132 provides power for the rotation of the cantilever 134 and the tension wheel 133 relative to the housing 15. In some embodiments, the torsion spring 132 can be torsionally twisted about its radial direction. In some embodiments, the two ends of the torsion spring 132 can be fixedly connected to the torsion spring mounting base 135 and the cantilever 134 respectively by welding or other means. In some embodiments, the torsion spring 132 is installed in a compressed or torsional state.

[0046] The tension pulley 133 is used to absorb vibrations and impacts from the rotation of the tension belt 131. In some embodiments, the tension pulley 133 may be made of a vibration-damping material, such as glass fiber-containing polyoxymethylene (POM) or ultra-high molecular weight polyethylene (UHMW-PE). In some embodiments, such as... Figure 4 As shown, the tensioning wheel 133 abuts against and presses the tensioning belt 131 on the side away from the main gear 111 and the auxiliary gear 121.

[0047] Cantilever 134 refers to the transmission and support component in tensioner 13. In some embodiments, such as Figure 4 and Figure 5 As shown, one end of the cantilever 134 is rotatably connected to the torsion spring fixing seat 135, and the other end of the cantilever 134 is rotatably connected to the rotating shaft 133-1 of the tension wheel 133.

[0048] The torsion spring mounting bracket 135 is used to fix one end of the torsion spring 132. In some embodiments, the torsion spring mounting bracket 135 can be fixedly connected to the motor bracket 113 by welding, bolting or other means.

[0049] In some embodiments, after the flipping assembly 1 is assembled (i.e., in the initial state), the torsion spring 132 is in a stored state (i.e., the torsion spring 132 is pre-compressed or twisted). The torsion spring 132 has a rebound force or a torsional force. The torsion spring 132 can rebound or twist under the action of the rebound force or the torsional force and gradually release the rebound force or the torsional force. Since the torsion spring 132 is fixedly connected to the cantilever 134, the torsion spring 132 rebounds or twists under the action of the rebound force or the torsional force, which can drive the free end of the cantilever 134 (i.e., the end where the tension wheel 133 is set) to rotate in the direction of pressing the tension belt, thereby driving the tension wheel 133 to abut against and press the tension belt 131, thereby increasing the tension of the tension belt 131. After a period of use, if the tension band 131 loosens (e.g., the length of the tension band 131 increases), the rebound force or torsional force of the torsion spring 132 will continue to drive the free end of the cantilever 134 to rotate, so that the tension wheel 133 continues to abut and compress the tension band 131, thereby keeping the tension band 131 under tension.

[0050] In some embodiments of this specification, if the tension band is too short, it is inconvenient to alternately sleeve the tension band onto the gear assembly. Furthermore, the tension band is prone to aging and loosening during the use of the flipping assembly, thus failing to maintain tension. However, the embodiments of this specification utilize the torsional force of a torsion spring to compress the tension band via a tensioning wheel. This not only increases the length of the tension band, facilitating the assembly of the flipping assembly, but also allows for continuous compression of the tension band to maintain tension even after it has aged and loosened.

[0051] Figure 6 This is the third structural schematic diagram of the tensioning member shown in some embodiments of this specification.

[0052] In some embodiments, such as Figure 6 As shown, the tensioning element 13 also includes a cam 136, which abuts against the cantilever 134. The cam 136 is used to adjust the rebound force or torsional force of the torsion spring 132, thereby adjusting the tension of the tensioning band 131. In some embodiments, the cam 136 (such as the shaft of the cam 136) is rotatably connected to the motor bracket 113.

[0053] In some embodiments, such as Figure 6 As shown, the tensioner 13 also includes a cam motor 137, which drives the cam 136 to rotate to limit the rotation angle of the cantilever 134.

[0054] The cam motor 137 provides power for the rotation of the cam 136 and is a device that converts electrical energy into mechanical energy. In some embodiments, the cam motor 137 is fixed to the motor bracket 113. The cam motor 137 can be any type of servo motor, stepper motor, etc. In some embodiments, the shaft (i.e., output shaft) of the cam motor 137 is fixedly connected to the shaft of the cam 136.

[0055] In some embodiments, when the cam motor 137 drives the cam 136 to rotate, different positions on the cam 136 can abut against the side wall of the cantilever 134, thereby adjusting the rotation angle of the cantilever 134, which in turn adjusts the rebound force or torsional force of the torsion spring 132, and thus adjusts the tension of the tension belt 131. The aforementioned rotation angle can be understood as the angle between the current position of a structure and its position in its initial state.

[0056] In some embodiments of this specification, the tension of the tension belt can be adjusted by setting a cam and a cam motor.

[0057] In some embodiments, such as Figure 5As shown, a vibration sensor 138 is provided on the cantilever 134. The vibration sensor 138 is used to acquire vibration data of the cantilever 134. Vibration data refers to data related to the vibration of the cantilever 134. In some embodiments, the vibration sensor 138 can be disposed at any position on the cantilever 134. For example, the vibration sensor 138 can be disposed at the middle of the cantilever 134.

[0058] In some embodiments, the cam motor 137 is further configured to adjust the rotation angle of the cam 136 based on vibration data collected by the vibration sensor 138. For example, when the tension wheel 133 abuts against and presses the tension belt 131 (i.e., in the normal state), the vibration of the flipper 14 flipping will be transmitted from the tension wheel 133 to the cantilever 134, and the vibration sensor 138 can collect the vibration data of the cantilever 134. However, when the tension wheel 133 does not abut against or press the tension belt 131 (i.e., tension failure), the vibration sensor 138 cannot collect the vibration data of the cantilever 134. At this time, the cam motor 137 can adjust the rotation angle of the cam 136, thereby causing the cam 136 to drive the cantilever 134 to rotate, so that when the tension wheel 133 abuts against and presses the tension belt 131, the tension belt 131 maintains tension.

[0059] In some examples in this specification, by setting up a vibration sensor and having it collect vibration data, it is possible to determine whether the tension belt is in a taut state. This determination result can be used to control the cam motor to drive the cam to rotate, thereby adjusting the tension.

[0060] Figure 7 This is a partial structural schematic diagram of the flipping assembly according to some embodiments of this specification.

[0061] In some embodiments, such as Figure 7 As shown, the rotating transmission shaft 122 is provided with at least two limiting holes 1221, and the motor bracket 113 is also provided with a solenoid valve 1131 and a limiting pin 1132. The solenoid valve 1131 is configured to control the limiting pin 1132 to insert into the limiting hole 1221.

[0062] The limiting hole 1221 and the limiting pin 1132 are used to limit the flipping angle of the flipping part 14.

[0063] In some embodiments, the limiting hole 1221 may be provided on the circumferential surface of the rotation transmission shaft 122. Furthermore, to avoid affecting the rotation of the rotation transmission shaft 122, the limiting hole 1221 is a blind hole (i.e., it does not penetrate the rotation transmission shaft 122). As an example only, the depth of the limiting hole 1221 may be 1 / 4, 1 / 5, etc., of the diameter of the rotation transmission shaft 122. The number of limiting holes 1221 is set based on actual requirements (such as the flipping accuracy of the flipping member 14).

[0064] In some embodiments, at least a portion of the limiting pin 1132 is movably disposed within the solenoid valve 1131, that is, the limiting pin 1132 can extend into or out of the limiting hole 1221 relative to the solenoid valve 1131, but cannot be completely disengaged from the solenoid valve 1131.

[0065] In some embodiments, the dimensions and shapes of the limiting hole 1221 and the limiting pin 1132 are mutually compatible. For example, if the limiting hole 1221 is a circular hole, then the limiting pin 1132 is a cylindrical pin with a diameter smaller than that of the limiting hole 1221.

[0066] Solenoid valve 1131 is used to drive limit pin 1132 to extend into or retract from limit hole 1221. In some embodiments, solenoid valve 1131 is fixedly installed on the side of motor bracket 113 facing the flip member 14; the direction of extension or retraction of limit pin 1132 matches the axial position of limit hole 1221.

[0067] In some embodiments, the solenoid valve 1131 can be either normally closed or normally open. A normally closed design means that when the solenoid valve 1131 is de-energized, the limit pin 1132 extends into the limit hole 1221, and the limit pin 1132 and the limit hole 1221 are locked. A normally open design means that when the solenoid valve 1131 is de-energized, the limit pin 1132 disengages from the limit hole 1221, and the limit pin 1132 and the limit hole 1221 are unlocked.

[0068] In some embodiments, after the user inputs a preset flip angle via a terminal device, the solenoid valve 1131 controls the limit pin 1132 to disengage from the first limit hole 1221, thereby unlocking the limit pin 1132 and the first limit hole 1221. At this time, the motor 112 drives the flipping component 14 to flip. When the flipping component 14 flips to the preset flip angle, the solenoid valve 1131 controls the limit pin 1132 to extend into the second limit hole 1221, thereby locking the limit pin 1132 and the second limit hole 1221, thus restricting the flipping of the flipping component 14 and locking the flip angle.

[0069] In some embodiments of this specification, the tilting angle of the tilting component can be locked by providing a limiting hole, a solenoid valve, and a limiting pin. Furthermore, for a normally open solenoid valve, the power consumption of maintaining the locked state between the limiting pin and the limiting hole is much lower than the power consumption of the motor 112 under the same function, thus reducing energy consumption.

[0070] Figure 8 This is a circumferential unfolded schematic diagram of a rotating transmission shaft according to some embodiments of this specification.

[0071] In some embodiments, such as Figure 8As shown, multiple limiting holes 1221 form a wavy groove 12211 on the flipping member 1; the length direction of the wavy groove 12211 is perpendicular to the axial direction of the rotation transmission shaft 122. The wavy groove 12211 refers to the groove formed by multiple consecutively opened limiting holes 1221. With this configuration, the flipping member 14 can achieve mechanical locking at multiple flipping angles. When mechanically locked, the motor 112 can be de-energized, which not only reduces overall power consumption but also eliminates the heat and noise generated when the motor 112 is continuously operating.
